TRUSSED BEAM.

Specification of Letters Patent.

Patented April 14, 1908.

Application filed. November 15, 1907. Serial No. 402,314.

To all whom it may concern:

Be it known that I, CHARLES H.WILLIAMS, Jr., a citizen of the UnitedStates, residing at Chicago, Cook county, Illinois, have invented acertain new and useful Im rovement in Trussed Beams, of which theollowing is a full, clear, and exact description, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings forming part ofthis specification, in which Figure 1 is a plan view, partly in section,of my improved trussed beam; Fig. 2 is a sectional view on the line 22of Fig. 1; Fig. 3 is a detail view of the thrust block; Fig. 4 is a planview, partly in section, of a modified form of beam; Fig. 5 is asectional view on the line 55 of Fi 4 Fig. 6 is a plan view, partly insection, o f a modified form of beam; Fig. 7 is a sectional view on theline 77 of Fig. 6 Fig. 8 is a plan view, partly in section,

of a modified form of beam and Fig. 9 is a sectional view on the line 99of Fig. 8.

This invention relates to a new and useful improvement in trussed beams,the object bemg to provide means for securing the bent end of thetension member in position in such manner that the brake head or springseat casting, as the case may be, may be removed without disturbing theintegrity of the truss. The trussed beam shown in the accompanyingdrawings is illustrated in the form of a brake beam, but it is obviousthat the construction could be employed in connection with body bolstersand truck bolsters.

In the drawings, referring to Figs. 1, 2 and 3, 1 indicates the coinression member in the form of a channel and 2 the tension member in theform of a fiat plate.

3 is the thrust block havin formed therein, and havin aIip or extension3' fitting over the end 0 the compression member and forming a seat forsaid com pression member to take up the end thrust thereof. Inassembling the parts the end of the tension member is passed through theopening 3", the end of the tension member t en being bent around the lip3 and against the rear face of the compression member.

4 indicates the socket wall of the brake head, which brake head afterbeing placed in position clamps the end of the tension an opening 3which the thrust block 6 is not provided with a lip 3 the compressionmember exerting its thrust directly upon the bent end of the tensionmember. The securing rivets 7 for the brake head or s ring seat castingin Fig. 4 are also arrangec at right angles to the rivet 5 shown in Fig.1.

In Figs. 6 and 7 the thrust block 8 is provided with a lip similar tothe lip 3', but in this instance the thrust block is made hollow and asingle rivet 9 is employed, said rivet being arranged similar to therivet 7 in Fig. 4.

In Figs. 8 and 9, the compression member 10 is in the form of an I-beam,and the thrust block is similar to the thrust block illustrated in Fig.3. The socket wall of the brake head or spring seat casting, as the casemay be, are made to conform to the rearwardly extending flanges of theI-beam.

I am aware that minor changes in the construction arrangement andcombination of the several parts of my device can be made andsubstituted for those herein shown and described without in the leastdeparting from the nature and principle of my invention.

Having thus described the invention, what is claimed as new and desiredto be secured by Letters Patent is:

1. In a trussed beam, the combination with a straight compressionmember, a tension member, and a block provided with an opening extendingparallel to the compression member and through which said tension memberpasses, the end of the tension member being bent around the end of thecompression member; substantially as described.

2. In a trussed beam, the combination with a compression member, of atension member, a block provided with an opening through which saidtension member passes, said block also having a lip or shoulderextending laterally beyond the end thereof and projecting over the endof the compression member, the tension member being bent around said lipand against the compression member; substantially as described.

3. In a trussed beam, the combination with a compression member, atension member, a block having an opening thereinextending parallel tothe compression member and through which opening said tension memberpasses, the endof the tension member being bent around the end of thecompression member; substantially as described.

4. In a trussed beam, the combination with a compression member, atension member, a block formed with an opening therein through which thetension member passes, said tension member being bent around the end ofthe compression member, and a mem ber provided with a socket which fitsover the end of the tension member and holds same in position;substantially as described.

5. In a trussed beam, the combination with a compression member, atension member, a block formed with an opening for the tension member,which tension member is bent around the end of the compression member, acastin which embraces the end of the tension member, and a fasteningmeans for holding said castingin position; substantiallyas described.

6. A thrust block adapted to be arranged in engagement with thecompression member of a trussed beam and provided with an opening forreceiving the tension member of said beam, and a lip projectinglaterally be= yond the outer end of said block so as to extend over theend of said compression member; substantially as described.

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses, this 17th day of October, 1907.
